Title (EN) LOW-WEAR BALL AND CUP JOINT PROSTHESIS
(FR) PROTHESE ARTICULAIRE A FAIBLE USURE
Abstract:
(EN) A ball (14) and cup (18) prosthesis is provided with articulating metal surfaces (25, 24), the surfaces (25, 24) having an area of intimate contact ($g(u)) in which the surfaces (25, 24) are formed on radii (R3, R1) which differ by at most 50 micrometers. The area of intimate contact ($g(u)) has a surface area that ranges from 0.12$g(p)R32 to 1.65$g(p)R32, and the centerline average surface roughness of the metal articulating surfaces (25, 24) in the area of intimate contact ($g(u)) preferably is not greater than 0.1 micrometers.
(FR) L'invention porte sur une prothèse d'articulation à rotule (14, 18) comportant des surfaces métalliques de contact (25, 24) en contact étroit ($g(u)) puisque leurs rayons respectifs (R3, R1) ne diffèrent que d'au plus 50 microns. La zone de contact étroit ($g(u)) présente une surface pouvant aller de 0,12$g(p)R32 à 1,65$g(p)R32, tandis que la rugosité moyenne en médiane des surfaces métalliques (25, 24) de l'articulation en contact étroit ($g(u)) ne dépasse pas 0,1 micron.
